When both glass and metal show reflections, what is a good basis for distinguishing them?

Answer and explanation

Correct answer: Look for transparency in glass and opaque shine in metal

Reflection alone does not identify a material because both glass and metal can reflect light. Glass commonly permits some transparency, showing objects or light through it, whereas metal is generally opaque and communicates its identity through dense, sharp shine. Therefore option A is the best basis. B, C, and D either erase the material difference or use irrelevant evidence.
